Optimality Conditions Applied to Free-Time Multiburn Optimal Orbital Transfers

Abstract : Although the Pontryagin maximum principle can be used to calculate candidate extremals for optimal orbital transfer problems, these candidates cannot be guaranteed to be at least locally optimal unless sufficient optimality conditions are satisfied. In this paper, through constructing a parameterized family of extremals around a reference extremal, some second-order necessary and sufficient conditions for the strong-local optimality of the free-time multiburn fuel-optimal transfer are established under certain regularity assumptions. Moreover, the numerical procedure for computing these optimality conditions is presented. Finally, two medium-thrust fuel-optimal trajectories with different number of burn arcs for a typical orbital transfer problem are computed, and the local optimality of the two computed trajectories are tested thanks to the second-order optimality conditions established in this paper.
